I think what he means is that there is a partition size limit for FAT32 when formating in WinXP (there is not if you use Win95, Win98 or WinME to do it though). There is not one when you format as disc to FAT32 on OSX. This is MSs way of forcing you to use NTFS on larger discs.

My question is on point #4. I was under the impression that when you use Bootcamp the Mac partiiton did not/could not see the Windows partition. Can it?
